Android guide for beginners

Android in the most famous operating system right now for mobile devices and tablets. Android developed by Android Inc. and later acquired by Google in 2005. Android OS is based on Linux kernel. That’s why it very much stable and free from many virus and bugs of windows.

Day by day android users are increasing in the world, daily thousands of android devices purchased in worldwide: in the form of smartphone, tablet, GPS navigation devices.

The main reason behind the huge popularity of Android is that it is highly customizable, android phones are available for every budget range e.g. users can buy an Android phone from Rs. 5000/- to Rs. 45000/-.

For new users it could be some difficult to understand working in this OS but soon when they are familiar with Android they may found this platform very easy and useful for their daily tasks. Once I get a chance to work on a Blackberry phone and it took my half day to sync old Nokia mobile contact to port in this device. A very simple thing that import export contact via sd card is missing such a high budget Blackberry device.

We can categorize Android phone into seven sections in view of operating aspect namely Home Screen (Panel, main screen), Application Drawer, Widgets, Status Bar, Settings , Apps (Applications & Play Store) and File manager. Now see one by one what does mean by these terms and how to use them in your mobile.

Note: All Android phones are different. Each manufacturer alters the software a bit, so the screenshots here may look a little different than the phone you have. Just keep in mind that the basics are essentially the same on most devices. We used Samsung Galaxy Tab-2 (7 in)  for this demonstration of android guide.

1. Android Guide for Home Screen –   Home screen or panel is the main screen that you see when you unlock/switched on your android mobile. This is like your computer’s desktop screen where all the shortcut of application and control of whole computer is available. In mobile you will found more than one screen, these may be 3,5,7 or user addable depends on the Android version and manufacturer. On this screen you will found short cut of your apps in the form of their icon and widgets. When you tap on these icon than selected apps will launch and by pressing back key you can close these apps. When you press home key these apps will continue to run in background and consume RAM and processing power. So it is always better to use back key in place of home if you do not want to use that app in background (this is used for multitasking). By long pressing home key you can check recently opened or running apps. In Android 4.0 and 4.1 one more modification available that you can see all the running apps by pressing multitasking key (looking two square imposing each other). When you pressed this key all the running apps shown you can go to them by tapping over them or swipe them to left to right to end the app.

When you want to place any short cut of any app just press app drawer icon and press and hold over selected app and placed it over the screen by moving left or right where you want to place them. For removing any shortcut icon from home screen, press and hold that icon and move towards trash pan and leave into it. By deleting shortcut your app will not uninstall you can again place short cut as like before (in some custom ROM like MIUI it will uninstall , because no app drawer in MIUI).

Some tips for home screen –

a. If you want to access more app on a single screen for your easiness you can place a folder on your favorite screen and move all apps shortcut icons inside this folder. You can now easily access them by tapping on folder icon in place of every time searching the app icon location.

b.Do not place many widgets on your screens as they always run in background in live condition e.g. weather widget it always run and also access internet as the sync settings to update continuously.

c. When not in use such apps like facebook , browser etc. close these apps by using back key your multitasking key as describe above to save memory and battery. ( see my previous post how to save battery in android and how to optimise RAM usage)

2. Android Guide for Application drawer – Application drawer is the place where all the installed apps of your mobile placed. You can access them by pressing app drawer icon in most mobile this is a hard key but in some tablet or mobile it can be placed on screen itself. The symbol of this is a many small squares in one icon. Using app drawer you can place your favriote apps icon on the screen, launch them. In Jellybean (4.1) or Icecream Sandwich (4.0) you can also place widgets using app drawer and uninstall the apps.

Widgets are also of two category one updates itself regularly to notify you the current status as like weather, system info widget etc. And second category widgets are not run in background they access you quick reachability of certain apps or system setting e.g. flash light widget, power widget.
